  • Abstract
    A WCDMA transmitter based on direct-digital RF modulator has a power control range of >90dB and achieves an ACPR of -58dBc with a channel power of -2dBm. Using an external PA with a power gain of 27dB, the measured EVM is <2% with signal levels from -35 to +25dBm. The chip is fabricated in a 0.13μm 1.2V CMOS process and occupies 4mm2.
